As part of the Superfund program, the U.S. Environmental Protection Agency (EPA) provides funding for groundwater remedies at Superfund-financed (i.e., 'Fund-lead') sites. A large percentage of these remedies are pump and treat (P&T) systems designed to restore groundwater and/or contain contaminants. On July 7, 2000, the EPA Office of Solid Waste and Emergency Response (OSWER) issued Directive No. 9200.0-33, Transmittal of Final FY00-FY01 Superfund Reforms Strategy, which outlined a commitment to optimize Fund-lead P&T systems. To assist EPA Regions in fulfilling this commitment, the EPA Technology Innovation Office (TIO) and Office of Emergency and Remedial Response (OERR) implemented a nationwide optimization project for Fund-lead P&T systems, Phase II (complete), the subject of this report, involved conducting an optimization evaluation at each of the sites selected in Phase I. The optimization evaluations were accomplished using the Remediation System Evaluation (RSE) process, which was developed by the U.S. Army Corps of Engineers as a tool for remedy optimization.
